cmGlobalGenerator: Do not persist alias targets across configures

Browse Source 
In `ccmake` a single global generator instance may be used for multiple
configure step runs.  The `cmGlobalGenerator::ClearGeneratorMembers`
method is supposed to clear global state that is specific to each
configure run but forgot to clear alias targets.

Fixes: #19457
